A phenolic resin, which is the reaction product of a difunctional phenol compound and a divinyl ether having a cycloalkane structure, is provided. The phenolic resin is used to form a difunctional epoxy resin. The resulting epoxy resin features relatively increased molecular weight, and it is used to impart flexibility or improved dielectric properties. It also provides improved moisture and water resistance when used to produce a cured epoxy resin article.
